Armpit fart. In particular, a picture of the process. Hilarious! Alice's expression in that photo is priceless.

It also reminds me of Remy's recent propensity to say "that's a snort!" every time he makes an audible fart. Daddy doesn't claim responsibility for teaching him that one, so maybe he just came up with it himself. OK, I'm shutting up about my own kid now.
